Abstract: A coal fired oxy boiler power plant is disclosed in which a steam coil oxygen preheater located on an oxygen line Air Separation Unit is thermally integrated with the condensate system. Thermal energy for the steam coil oxygen preheater is provided via an extraction line connected to a steam extraction port of an intermediate pressure steam turbine. A drain line of the steam coil oxygen preheater fluidly connects the steam coil oxygen preheater to a point of the Rankine steam cycle fluidly within the condensate system.

Abstract: A power plant for the generation of electrical energy with a system (1) for processing flue gases resulting from a combustion of fossil fuels comprises, according to the invention, an adiabatic compressor (5) for a first low-pressure compression of the flue gases and a second multi-stage, low-pressure flue gas compression system (14) and a multi-stage, high-pressure CO2 compression system (15), where both the low-pressure flue gas compression system and the high-pressure CO2 compression systems are combined in one single machine (C2) and are arranged on one common shaft (16) driven by one common driver (17). A heat exchanger (8) facilitates an improved recovery of heat resulting from the cooling of the adiabatically compressed flue gases. The invention allows an improvement of the overall power efficiency of a power plant integrated with this processing system as well as a reduction of investment cost.
